SPECIFICATION forming part of Letters Patent No, 639,268, dated December 19, 1899. Application filed August 7,1899. Serial No. 726,364. (No model.)

To all whom it may concern.-

Be it known that I, AROHIBALD N. MCBEAN,

a citizen of the United States, residing in West I-Ioboken, county of Hudson, in the State of New Jersey, have invented certain new and useful Improvements in Window Frames; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, making a part of this specification, in which- Figure l is a horizontal sectional view of a window-frame made according to my invention. Fig. 2 is a like view of an ordinary window-frame, here introduced to more fully illustrate the differences in character and construction between my invention and structures previously in use.

Like reference-letters indicate corresponding parts in both figures of the drawings.

The figures show one side rail of a windowsash and adjacent parts of the window-frame, it being of course understood that the opposite side of the sash, window-frame, &c., is of like construction in each case.

The object of this invention is to provide a window-frame which will be less pervious to drafts and air-currents than those heretofore in use and one which is more economical in cost of manufacture and construction. It comprises certain novel combinations of parts whereby these objects are effectually obtained.

A is the inside hanging-stile, and B is the outside hanging-stile, of a window-frame,

which are joined by the pulley-stile O. The edge of the window-sash D (of which the glass is indicated at a) runs in contact with the surface 12 of the pulley-stile, and the weight 0, which balances the sash, runs in the box cl at the opposite side of the pulley-stile between the latter and the adjacent surface of the brickwork or wall, which said surface is indicated at e. The sash D, as shown in the drawings, is the inner sash of an ordinary two-sash window, the outer edge of the sash resting against the parting-rail F, behind which, at G, but not shown in the drawings, is situated the usual outer sash of the window. To this point in the foregoing description the parts referred to as in the two figures of the drawings are identical; but it may here be noticed that in Fig. 2, which shows the old or ordinary construction, there is fast upon the outer surface of the inside hanging-stile A a strip I, in which is a groove f, into which is fitted the tongue g of the window-jamb J, that the edge a next adjacent to the sash of the strip I is flush with the adjacent edge surface I) of the inward hanging-stile, and that a strip K (usually designated as a stop-bead or window-stop) is placed upon the two edge surfaces ct I), while the edge 0 of the strip or stop-bead K is adjacent to and parallel with the sash, so that in conjunction with the parting-rail F it provides the guide or way in which the end of the sash may move up and down.

In practice the strip I and stop-bead K are made of oak or other wood of comparatively ornamental and pleasing appearance and cover the surfaces of the inside hanging-stile A, which with the outside hanging-stile and the pulley-stile are usually of cheaper and inferior material. This construction, it will be noticed, provides a straight unbroken joint from inside to outside, from a to 12 which joint by even the slightest shrinking of the wood is enlarged and permits drafts, air-currents, and wind to pass freely into the apartment to the annoyance and discomfort of the occupants. It will be further observed that with this, the ordinary construction, the strip I is separately shaped and applied in place and that this is the case also with the stop-bead K, the attachment being usually made with nails or screws and the outer surfaces stained or varnished, the nailing requiring an expert carpenter and the staining or varnishing a workman equally skilled in the painters trade.

Referring now to Fig. 1, which illustrates my invention, it will be noticed that: I eliminate the strip I of Fig. 2 and insert the tongue g of the jamb J in a groove g in the inside hangingstile A, (the jamb being thus fitted directly to and against the hanging-stile,) and that instead of applying the usual separate stop-bead I provide a window-stop L, which is rabbeted at its inner side, as shown at m n i", this rabbet m n r being so shaped and proportioned as to be secured to the angular edge or corner 8 of the inside hanging-stileA with its edge surface m bearing against the contiguous surface in of the jamb J and its surface m bearing against the edge surface r of the hangingstile A and secured thereto, while its third surface s rests against the edge a of the sash to act in conjunction with the parting-rail to hold and guide the sash in position and to permit the raising and lowering of the sash. In order to abut the edge m of the crown c of the window-stop against the jamb, the said crown is extended along the surface of the inside hanging-stile between the edge or corner 3 of the said stile and the surface of the jamb. By this means I provide a broken joint between the window-stop on the one hand and the inside hanging-stile and the jamb on the other. This breaking of the said joint obstructs and prevents the passage of drafts and air-currents through the joint from the outside, and thereby obviates a material defect which, as hereinbefore explained, inheresin the old or usual arrangement of parts illustrated in Fig. 2.

In practice I prefer that the rabbet in the window shall be so proportioned as to provide a space or cavity 1)" between the crown c of the window-stop and the opposing surface of the inside hanging-stile in order to permit any shrinking of the material which may occur to be compensated by moving or adjusting the Window-stop nearer to the sash.

By means of my invention I not only provide a wind or draft-tight window-frame in the respects hereinbefore explained, but I also securean important economy in the cost of the window. Instead of being required to manufacture, handle, apply in place, varnish, and finish two separate pieces of material I am required to perform these operations with only one piece of material. At present prices of materials and skilled labor the economy thus secured is certainly not less than thirty cents per window fitted with frames made according to my invention as compared with the cost of those of the old or ordinary construction. Moreover, as the crown c" of the window-stop L is integral with its side strip f an unbroken external surface is presented to sight and very much n eater work is provided than is possible when the surface is divided by a joint that is liable to open to the dimensions of a crevice from shrinking of the wood.

hat I claim as my invention is 1. The combination with the inside hanging-stile and jamb of a Window-frame, of a rabbeted window-stop affixed to the stile adjacent to the sash to hold and guide the same and with its crown extended along the stile with its edge abutting upon the jamb, substantially as herein set forth.

2. The combination with the inside hanging-stile and jamb of a window-frame, of a rabbeted window-stop affixed to the stile adjacent to the sash to hold and guide the same, and with its crown extended along the stile and abutting upon the jamb, with a cavity between the crown and the adjacent surface of the inside hanging-stile, whereby said window-stop may be adjusted to the sash, substantially as herein set forth.

3. In a window-frame the combination with a grooved inside hanging-stile andatongued jamb fitted thereto, of a rabbeted windowstop-placed on the stile adjacent to the sash to hold and guide the latter and with its crown extended along the stile and abutting upon the jamb, substantially as herein set forth.

t. In a window-frame the combination with a grooved inside hanging-stile and a tongued jamb fitted thereto of a rabbeted windowstop placed on the stile adjacent to the sash to hold and guide the latter and with its crown extended along the stile and abutting upon the j amb with a space or cavity between the crown and the surface of the stile, substantially as herein set forth.
